WebIn chemistry, a bicyclic molecule (from bi 'two', and cycle 'ring') is a molecule that features two joined rings. [1] Bicyclic structures occur widely, for example in many biologically … WebBecause hemiacetal and hemiketal reactions can occur with intramolecular groups, a cyclic structure is formed with an oxygen as a member of the ring. This intramolecular reaction occurs at a significant rate without enzymes. Combined names such as glucopyranose, etc. are often used.
